Typical Application Circuit for LTC3265IFE Low Noise +7V/-2V Power Supply from a Single-Ended 5V Input Supply (Frequency = 200kHz)

Typical Application Circuit for LTC3265IFE Low Noise +7V/-2V Power Supply from a Single-Ended 5V Input Supply (Frequency = 200kHz). The LTC3265 is a low noise dual polarity output power supply including a boost charge pump, an inverting charge pump and two low noise positive and negative LDO post regulators. The boost charge pump powers the positive LDO post regulator while the inverting charge pump powers the negative LDO regulator
